IMPROVEMENT IN BOTTLE-STOPPERS.

Specication forming part of Letters Patent No. 120,821, dated November14, 1871.

To all whom t may concern:

Be it known that I, GARRETT G. LOWE, of the city and State of New York,have invented a new and Improved BottleStopper; and I do hereby declarethat the following is a full and exact description thereof, referencebeing had to the accompanying drawing and to the figures of referencemarked thereon.

Figure 1 is a full View of stopper. Figs. 2 and 3 are longitudinalsections. Fig. 4 is a view of one of the staves. Figs. 5 and 6 arecross-sections.

My expansible stopper is made of three or more staves within anIndia-rubber cylinder, that is closed at one end and at the other endsurrounds a conical washer, through which a screw passes and acts upon asecond conical washer at the other end of the staves. By thisconstruction the staves can be spread to enlarge the stopper or thereverse.

The staves c c are made as segments of a cylinder dividedlongitudinally, and with inclined ends to iit the conical washers b andc. I have shown six of these staves, but they may bemore or lessnumerous. The screw d passes through the cone b and screws into the conec, and the head projects above the cone b. The cylinder of rubber esurrounds these parts, as represented, and forms the bottle-stopper, andthis elastic cylinder can be distended to suit the size of the bottleneck by drawing the cone c toward the cone b by the screw d, or thereverse movement allows the cylinder e to contract.

I claim as my invention- The staves a a, between the cones bc and withinthe rubber cylinder e, in combination with the screw d for distendingthe cylinder e of the bottlc-stopper, as set forth.

GARRETT O. LOWE.
